For a while now (and since the upgarde to the latest version, but not blaming that) completed WUs are not uploading automatically. I have to go Projects, select the project (Seti@Home) and click Update.

1) 24 hours before deadline.
2) Connect Every X before deadline.
3) 24 hours after task completion.
4) Immediately if the upload completes later than either 1, 2, or 3 upon completion of the task.
5) On a trickle up message.
6) On a trickle down request.
7) On a server scheduled connection. Used, but I am not certain by which project.
8) On a request for new work.
9) When the user pushes the update button.
10) On a request from an account manager.
11) Report immediately every task, if "No new Task" is set.
12) Report immediately if CPU or network time-of-day override starts in the next 30 minutes. (BOINC 7.0)
13) When minimum work buffer is reached. (BOINC 7.0)Jord

#13 is a repeat of #8. This is when the work fetch will occur.BOINC WIKI

Well, yes and no. The list of when reports happen is one for BOINC 5, 6 and 7. In BOINC 5 and 6 work requests happen at random, it seems. So better to differentiate between just a mere work request and when minimum work is reached. Jord

No it wasn't. It was when the work on hand dropped below the sum of "connect every X" and "extra work". On 7 that changes to "connect every X". BOINC WIKI

I think that an other point can be as soon as a "high task priority" is uploaded.

Not always. A low resource share task is likely to run high priority early, complete early and then sit there for a while. A task running in high priority gets the same treatment as any other task once it is done.BOINC WIKI
